Definitions

  • the invention relates to a method of indicating settings of remote-controlled, zonal control members for metering a supply of ink and/or dampening solution at a central remote-control console of a rotary printing press, the settings being converted into display signals which are rendered visible by light-emitting diodes associated with respective inking and/or dampening zones so that they represent the inking and/or dampening profile.
  • the same display signals are used for two separate displays of which one is in the form of a coarse analog display of the inking and/or dampening profile, providing the base value for the settings for the coarse adjustment of the control elements, and the other in the form of a fine digital display, indicating the fractional value for the settings for the fine adjustment of the control elements.
  • the invention provides, at relatively little technical effort, a method for indicating information which consists of a base part which may be indicated in integer form and a small fractional, remaining part, wherein the base information indicates the inking and/or dampening profile in analog form, and simultaneously, the remaining information is indicated in digital form, for a fine adjustment of the individual inking and/or dampening zone members that is still within the possibility of the control members to the degree of resolution and reproducibility of the control elements.
  • the rough analog display is provided by means of vertical, zonal rows of light-emitting diodes and the fine digital display is provided by means of a digital signalling device additionally assigned to each row of light-emitting diodes.
  • a possible manner of advantageously performing the method according to the invention provides that the two displays, both the rough-analog first display as well as the fine-digital second display to be effected by the zonal light-emitting diodes, the fine-digital display is superimposed upon the rough-analog display in the zonal columns of light-emitting diodes.
  • This method of indication makes use of the previously existing LED display for representing the inking profile.
  • the simultaneous use of the column of light-emitting diodes both for the rough as well as for the fine display dispenses entirely with any additional, separate display, as well as with any associated electronics. This results in considerable cost savings.
  • the rough-analog display is effected by continuously illuminating individual light-emitting diodes of the corresponding zonal columns, and the fine-digital display by simultaneously flashing some of the corresponding light-emitting diodes of the corresponding individual zonal columns.
  • the fractional value of the display signal lying between the latter response threshold and the response threshold of the next higher light-emitting diode and which cannot be shown in the analog display is fed to a fine digital display. Due, for example, to a decimal fine division of the spacing of a pair of light-emitting diodes respectively disposed above one another with successive integer numbers, a greater display accuracy of the settings and thereby greater adjustment accuracy of the zonal control elements is attained.
  • An exemplary device for performing the method of the invention includes vertical columns of light-emitting diodes provided for the coarse analog display of the inking and/or dampening profile as the base value for the settings of the coarse adjustment of the control elements, and digital indicating devices which provide the fine digital display for indicating the fractional values of the display signals that cannot be shown in the analog display.
  • Such an arrangement device permits the operating personnel to have not only a rapid and comprehensive view of the actually existing inking profile as analog information, but also delivers simultaneously digital information regarding the fine adjustment state of the individual zonal inking and/or dampening control elements, whereby actions in the form of fine corrections can be effected in the inking and/or dampening-solution feed in order to achieve high printing quality in the shortest time.
  • the digital signalling devices are constructed as numerical displays associated with each of the zonal columns of light-emitting diodes and are positioned thereabove.
  • the fractional (intermediate) values of the setting between two consecutive light-emitting diodes are made clearly visible to the operating personnel in the form of decimals, for example, which is of considerable advantage when great qualitative demands are made upon the accuracy of the printed product.
  • the same vertical columns of light-emitting diodes provide both the coarse analog display of the inking and/or dampening profile as base value for the settings of the coarse adjustment of the control elements as well as the fine digital display for indicating the fractional values of the display signals that cannot be shown directly in the analog display and whereby constantly illuminating light-emitting diodes are used for the coarse analog display and flashing light-emitting diodes for the fine digital display superimposed on the coarse analog display.
  • the printer can, within a very brief time, obtain a clear overview, broken down into rough and fine information, of the inking and/or dampening profile and the need for corrective adjustments of the inking and/or dampening control members.

  • FIG. 2 a block diagram of an indicating device according to FIG. 1;
  • FIG. 3 is a fragmentary, diagrammatic view of a first embodiment of the indicating device
  • FIG. 4 is a fragmentary, diagrammatic view of a second embodiment of the indicating device
  • FIG. 5 is a block diagram of the control circuit arrangement of the invention.
  • FIG. 6 is a block diagram of the LED gating and control arrangement.
  • FIG. 7 is a circuit diagram showing the clock pulse generator and the clock decoder in greater detail.
  • FIG. 8 is a circuit diagram showing the zone decoder in greater detail.
  • FIG. 1 shows part of a control desk 1 of a central remote-control console, showing individual inking zones of an inking unit which is conventional and therefore not further illustrated and described.
  • Zonal light-emitting diode displays in the form of vertical columns 2 of light-emitting diodes have, depending upon the desired indicating accuracy, a number of light-emitting diodes 3 with vertically increasing interger numbers 4 which are assigned to (associated with) each inking zone.
  • a vertical column 2 of light-emitting diodes comprises twenty individual light-emitting diodes 3 positioned one above the other.
  • control instruction can be issued for reducing or increasing the zonal ink feed.
  • FIG. 1 represents a section of the control desk 1 of the central remote-control console for the adjustment of inking zones over an area of four inking zones.
  • an inking profile 7 By connecting lighted ones of the activated light-emitting diodes 3, there is indicated, across the width of the control desk 1, an inking profile 7 as a rough qualitative indication of the actual momentary state of inking.
  • the inking profile 7 extends from left to right through the eight, eleventh, tenth, and seventh light-emitting diodes 3.
  • the inking profile is adequately determined.
  • the ink feed setting to be measured is picked up directly by a sensor 8, e.g. a generally conventional potentiometer physically connected with the ink feed member, and is fed therefrom, in the form of an analog signal, from the sensor 8 into an analog-digital signal converter 9, to which it is connected.
  • the signal converter 9 with a decoder converts the analog value of the input signal into corresponding individual digital values which may be used for displaying the analog value on one light at the time.
  • the display may be arranged as a rough 2, and a fine display 6 disposed parallel to one another and extending directly from the signal converter 9. The converted display signal is accordingly fed to both the rough display 2 and the fine display 6, the two displays having different degrees of resolution.
  • the display signal is rendered visible in the rough display by the activation of one light-emitting diode 3.
  • the illumination of corresponding light-emitting diodes 3 in different zones provides a rough analog indication for the inking profile as described above.
  • this display may provide a rough indication.
  • the activated light-emitting diode 3 does not provide any information about the fractional values of the signal between the response thresholds of two adjacent light-emitting diodes 3.
  • the additional fine display is used to indicate these fractional values in addition to the rough display. Accordingly, the value of the display signal which exceeds the lower response threshold of a light-emitting diode 3 is fed into the numerical display 6 and provides a fine display in digital numerals. The degree of resolution of this fine digital display may be considerably greater than that of the rough analog display for the inking profile.
  • the light-emitting diodes 3, as described above, indicate the coarse setting of the ink feed control members and the associated fine digital display 6 indicates, using decimal divisions that the control member for the corresponding inking zone is opened additionally, in this case, by the value of 0.4 above the numerical value associated with the ninth light-emitting diode 3, shown in full, assuming the diodes 3 are numbered 1-9.
  • a zero in the first numerical display 6 means that, in this case, the signal value corresponds exactly to that indicated by the ninth light-emitting diode 3, shown in full.
  • a single decimal place in the digital numerical display 6 is generally sufficient. The accuracy obtained thereby normally fully meets the highest demands on the printed product with respect to the inking quality thereof.
  • an optically operating indicating device 6 consisting of a single light, emitting light pulses, wherein the number of pulses emitted, represents the fractional value of the display signal.
  • a simplification in the implementation of the indicating method is effected in an especially advantageous manner such that the light-emitting diodes 3 already employed for the rough display of the inking profile 7 are also used for the fine display by means of pulses flashing the decimal value, as described above, so that an additional display is thus completely dispensed with.
  • FIG. 3 shows in a preferred embodiment having sixteen individual light-emitting diodes 3 positioned one above the other combined into vertical columns 2.
  • the method of indication is provided such that the light-emitting diode 3 that is activated for the rough analog display of the inking profile 7 glows continuously with the same intensity, whereas another light-emitting diode 3 in the same column 2 having a different integer number e.g. 4 by flashing or by glowing more weakly provides the additional decimal information.
  • continuous illumination of the eighth light-emitting diode 3 and flashing of the twelfth light-emitting diode indicates that the control member for the associated corresponding inking zone is opened by a value of 12/16 above the level indicated by the eighth light-emitting diode 3.
  • Still another preferred embodiment shown in FIG. 4 has a similar construction as that described above and shown in FIG. 3, with respect to the provision of the rough analog display of the inking profile 7.
  • the essential difference between this embodiment and the former is that the degree of resolution of the fine digital display has been doubled by the possibility of activating either one or simultaneously, two consecutive light-emitting diodes 3 as shown in the second row from the left.
  • the simultaneous flashing of two consecutive light-emitting diodes 3 additionally indicates a fractional value equal to a half increment above that indicated by the first flashing diode.
  • the constant illumination of the eleventh light-emitting diode 3 and simultaneous flashing of the seventh and eighth light-emitting diode 3 indicates that the control member associated with this inking zone is increased by a value of 15/32 above the response threshold of the eleventh light-emitting diode 3.
  • a display with such a high degree of resolution meets even the highest requirements imposed on the inking quality of a printed product.
  • FIG. 5 shows a block diagram of the LED display control circuit.
  • a clock generator 10, connected to a clock decoder 11 produces all the timing, scanning and sequencing functions required for the remaining circuit.
  • An analog switch 12 containing 32 individual switches that are activated sequentially from lead C from the clock decoder 11 operates to sequentially and periodically connect the sensor 8 (FIG. 2) for each ink zone control-member to the analog-to-digital converter (ADC) 9, through a scale adapter 13 that serves to adjust the potential coming from the 32 sensors 8, one at a time, to a voltage range suitable for the ADC 9.
  • the most significant leads 15 are connected to a 4 to 16 coarse decoder 16 with 16 individual output leads, shown as a single bus 16a, and the four least significant leads are connected through a 4 -bit adder 18 to the fine decoder 19, which has 16 output leads shown as bus 19a.
  • the coarse decoder serves to energize one of the 16 LED's in each of the 32 columns 2 of the LED matrix 22, each representing an inking zone, one, at the time in synchronism with the scanning of the corresponding 32 switches of the analog switcher 12.
  • each column 2 consisting of 16 LED's is activated with a negative potential at exactly the same time that the one row 26 each representing all the 32 LED's in each row is energized with a positive potential. Since each LED is essentially a diode it is well known to address one diode at the time in a matrix by simultaneous activating the row and the column with a positive and negative potential respectively. This method is also known as strobing and is widely used for electronic displays such as in calculators and many other devices. The strobing is done at such a high speed that the human eye cannot perceive the individual LED's as flashing and therefore sees the LED's as continuously lighted unless some additional lower flashing frequency is superimposed on the scanning frequency.
  • the 16 disjunction gates 21 consist of 16 row drivers for the matrix 22, and is drawn in more detail in the dashed box 21 of FIG. 6. Each driver is driven by a two input OR-gate 21a, each driving a row driver 21b which produces at its output lead a positive potential if one of the OR-gate inputs is energized.
  • One input to all the 16 OR gates is connected to 16 outputs from the coarse decoder 16 (FIG. 6), while the other input is connected to the fine decoder 19. Additional control circuitry and components shown in FIG.
  • An Enable switch is connected to the four bit adder 18 and to the fine decoder 19 via logic 25, via lead 24.
  • FIG. 7 shows details of the clock pulse generator 10 and the clock decoder 11 which in turn drives the zone decoder 20 and produces 32 individual zone select pulses, which periodically sequentially enable each of the 32 columns 2 of the LED matrix 22, as described in detail above. Details of the zone decoder are shown in FIG. 8.
  • the zone decoder 20 is seen driven by the clock decoder output lead c.
  • the zone decoder 20 advances by a count of one each time a complete reading of the 32 analog switches has been completed by the ADC 9 and decoded by the coarse decoder 16 and the fine decoder 19, and displayed for a finite length of time by the selected LED at the matrix crosspoint of the selected row and selected inking zone column.
  • a four bit adder 18 and a logic circuit 25 is shown connected to the fine decoder 19 for operating the second flashing LED in one column.
  • the additional half increment is enabled by the lead a from the ADC 9 which is connected to a .carry-in lead (C in) of the four bit adder 18.
  • This additional half increment is now indicated by the carry-in by raising the binary output from the four bit adder 18 to the fine decoder 19, which, as a result enables the next higher numbered output lead of the 16 leads comprising the bus 19a from the fine decoder 19 to the 16 disjunction gates 21.
  • the logic circuit 25 is driven from a carry out lead (C out) from the four bit adder 18 so that, in case an output carry is created by the binary number received on leads 17 and the presence of a carry in result in a carry out, the output from the fine decoder is raised by still another increment.
  • circuits involved in these operations are all well known and conventional.
  • Four bit adders with carry in and carry out are known as full adders and are manufactured by Motorola Co. as MC 14008B and the decoders may be Motorola circuits MC 14514B or any other similar, suitable circuit.
